So manufacturing of ultra high strength X-120M line pipe through J-C-O-E technique is more convenient and cost effective as for as forming force (Tonnage) tooling are required.In J-C-O the formation is carried out by incremental pressing with required number of strokes to form the high strength line pipe with less forming force (Tonnage) and less amount of tooling.Deformation-enhanced hierarchical multiscale structure ·In this study,a suitable method to simulate pipe-manufacturing processes (i.e.,bending,unbending,and flattening) was developed to reproduce the process and the mechanical properties of the pipe.To verify the reliability of the strain distribution and plastic deformation behavior predicted by the proposed method,experimentally-derived strain by digital image correlation (DIC) and finite Degradation Mechanisms and Mitigation Strategies of Nickel Oct 21,2019·Abstract.The demand for lithium-ion batteries (LIBs) with high mass-specific capacities,high rate capabilities and long-term cyclabilities is driving the research and development of LIBs with nickel-rich NMC (LiNi x Mn y Co 1xy O 2,\(x \geqslant 0.5\)) cathodes and graphite (Li x C 6) anodes.Based on this,this review will summarize recently reported and widely recognized studies of
